ABSTRACT:
A slim-line direct current (DC) brushless motor for automotive and HVAC applications utilizes a sleeve bearing assembly to rotatably couple an exterior rotor to an interior stator. The rotor includes a flat permanent magnetic and the stator assembly includes a flat coil. The flat coil is made from a stamped copper member. The rotor is staked to the bearing assembly by a hub-shaft. A cooling fan is disposed on the top of the rotor to cool internal control circuitry within the motor. The motor is easily assembled and has a minimal number of moving parts.
